ANALOG OUTPUT (PHOTON) doesn't work

Do you get the same behavior if you use pin A7 ?

PWM Rgb LED on the Photon

I am trying to get an RGB Led to flash the 3 colors. I have some code which works fine on the Core and I used pins : A5 = Red, A6 = Green, A7 = Blue I read this post about the changes in pins So I plug the Photon into the same breadboard and I swap the pins : A4 = Red, A5 = Green, A7 = Blue Except now only the Blue color shows. Is there something else I need to do? Are the names A4 / A5 invalid (I would have expected an error if so).
